If you are thinking about the Magellan I would recommend the Meridan over the Sporttrek as it allows the use of secure digital cards so it makes it's memory virtually unlimited. I don't think it is a whole lot more than the Sporttrek models.

I use a Magellan and I love it. I have had no problems except when I ran it through the wash machine and even then Magellan fixed it for free.

Heh... my Explorist went through the washer and the dryer last week... I took it apart and dried it off inside and out... works fine!
